SIPECIFIGATION forming part of Letters Patent No. 657,543, dated September 1 1, 1 900. A li ation fil d November 29, 1899. Serial No. 738,694. (No model.)

fication.

This invention relates to sewing-machine attachments, and more particularly to foldgages, one object of the invention being to provide an improved device of this character which can be readily and quickly shifted from its operative or working position into an inoperative position without completely detaching the same from that part of the sewingmachine to which it may be secured and which also can be, when connected to the pressen foot bar, shifted therewith on the shifting of the presser-foot, thereby to raise the fold-gage out of engagement with the work. I

A further object of the invention is to provide an improved fold-gage which can be readily and accurately adjusted to obtain various widths of hems, the construction thereof being such that the work will pass freely over the same and also be elfectively creased.

In the drawings accompanying and forming part of this specification, Figure 1 is a per.- spective view of the head of a sewing-machine, having a part thereof broken away, showing this improved fold-gage in position. Fig. 2 is a top view ofthe fold-gage detached from such head. Fig. 3 is a view. of the foldgage bar or arm and the means for supporting the same, taken at right angles to Fig. 2. Fig. 4 is a perspective view of the foldgagesupporting bar partly broken away. Fig. 5 is a perspective view of the block used herein to secure such supporting-bar in engagement with the sewing-machine head. Fig. 6 is a cross-sectional view taken in line a a, Fig. 3, looking toward the right. Fig. 7 illustrates in full lines the working position and in dotted lines the inoperative position of the fold-gage while in rigid engagement with:

the presser-foot bar, which is shown in section. Fig. 8 is a sectional View of the guide or gage arm, taken in line b b, Fig. 2.

Similar characters of reference designate like parts in all the figures of the drawings. In using a fold-gage in sewing-machines it is oftentimes desirable temporarily to dispense with such gage and sew portions of the work without the same, and to accomplish this object I have provided an improved fold-gage so connected with the sewing-machine that it can be quickly shifted from its working position into an inoperative position, or vice versa, without the necessity of detaching the same from the sewing machine.

lifting of the presser-foot to also lift the gage out of engagement with the work, and to accomplish this result with facility I have provided an improved fold-gage which, while rigidly secured to the presser-foot bar for movement therewith, is also adjustable independently of such bar, so as tothrow the same into an inoperative position without the necessity of detaching the gage from the sewing-machine. This improved fold-gage in the form herein shown and described and which may be its preferred form, if desired, comprises a supporting member or bar 2, jointed in some suitable way to a bracket 3, adapted to be secured to a part of the sewing-machine. In the present instance this supporting-bar 2 is provided with a pair of laterally-extending perforated ears 4, intermediate which the end 5 of a bracket 3 is pivoted by a suitable pivot, shown herein as a, screw 7. This bracket 3 may be formed for attachment to some suitable part or member of a sewing-machine, and since it could be secured in some forms thereof by mere modification of details to ried thereby it follows thatthe part or member to which it is attached need only be some suitable member in position and adapted for the purpose. In the present instance, how- I ever, it is shown projecting through a slot 8 in the head and connected with the presserfoot bar or member 9, being provided with an openinglO, through which said bar extends, such bracket being rigidly secured thereto by a suitable fastening device, such as a screw 2, and also having a projection or arm 13, adapted to project into a slot of or engage with some suitable fixture(not shown) of the sewing-machine head, whereby the rigid position of the bracket is insured, while also a positive torsional or rotary movement of the presser-foot bar is positively prevented. To

the head or arm or to an operative part car-' Moreover, it is also desirable at times on the amt a i may be swung into and out of its working position, and means working in said slot for detachably securing said gage to said head, the organization being such that on the shifting of such presser-foot bar the gage, by means of its slot, can move with said bar relatively to said'head.

6. The combination, with a fixed member and with a presser-foot bar of a sewing-machine, of a foldgage comprising a bracket secured to said bar; a supporting-bar jointed to said bracket for shift-able movement independently thereof and having a guide-arm,

whereby said guide-arm is shiftable into and out of engagement with the work; and means for securing said supporting-bar in engage.

ment with said fixed me mber,thereby to maintain the guide-arm in its working position.

7. The combin ation,withasewing-machine head and witha presser-foot bar mounted thereon, of a fold-gage comprising a bracket secured to said bar and having an arm in engagement with said head, a supporting-bar jointed to said bracket and having a guidearm, whereby said arm is supported for swinging movement into and out of engagement with the work and means for maintaining said gage in its working position.

8. Thecombination,withasewing-machine head and with a presser-foot bar mounted thereon, of a fold-gage comprising a bracket secured to said bar and having an arm in engagement with said head to prevent torsional or rotary movement of said presser-foot bar; a supporting-bar jointed to said bracket and having a guide-arm, whereby saidarm is supported for swinging movement into and out of engagement with the work; and means for securing said supporting-bar in movable eugagement with said head, thereby to maintain said guide-arm in its working position.

9. The combination,with a sewing-machine head and with a presser-foot bar mounted thereon, of a fold-gage comprising a bracket secured to said bar; a supporting-bar. having a slot therein and a guide-arm and jointed to said bracket for swinging movement; and a guide-block for the slot of said bar and adapted to be secured to said head, whereby on the movement of said presser-foot bar the supporting-bar is movable therewith relatively to said guide-block.

10. The combination, with a sewing-ma chine head and with a presser-foot bar mounted thereon, of a fold-gage comprising a bracket secured to the said bar for movement therewith and adjustment thereon; a supportingbar jointed to said bracket for swinging movement and havinga slot therein; a guide-block carried by said bar-and adapted to be rigidly secured tosaid head, whereby on the movement of said presser-foot bar the supportingbar is movable therewith relatively to said guide-block; and a guide-bar adj ustably carried by said supporting-bar.

11. The combination, with a sewing-machine head and with a presser-foot bar'mounted thereon, of a fold-gagecomprising a bracket secured to said bar for movement therewith and adjustment thereon and having an arm in engagement with said head, a supporting-bar jointed to said bracket for swinging movement and having a slot therein; a guide-block carried by said bar and adapted to be rigidly secured to said head, whereby on the movement of said presser-foot bar the supporting bar is movable therewith relatively to said guide-block; and a guide-bar adjustably carried by said supporting-bar, said guide-bar having a beveled guiding edge for the fold of the hem.

12. The combination, with a sewing-machine head and with a presser-foot bar carried thereby, of a fold-gage comprising a supporting-bar supported by said presser-foot bar for shiftable movement into and out of its working position, said fold-gage having a detachable connection with said head, and an adjustable guide-arm carriedby said supporting-bar.

13. The combination, with a sewing-machine head and with a presser-foot bar mounted thereon, of a fold-gage comprising a bracket secured to said bar; a supporting-bar pivoted to said bracket; means for removably securing said supporting-bar to said head; and an arm adjustably carried by said supporting-,

sewing-machine, and a supporting-bar having a guide-arm and jointed to said bracket for swinging movement and having a slot for the reception of means whereby said bar may be detachably secured to a fixed member of a sewing-machine.

16. A fold-gage comprising a supportingbar carrying means for shiftably attaching it to a fixed member and means for supporting it on a movable memberof a sewing-machine, and a guide-arm carried by said supportingarm.
